Description

Technical Field

[0001] The utility model belongs to the technical field of construction of post-cast strips of basement side walls of industrial and civil buildings, and particularly relates to a post-cast strip structure of basement side walls. Background Art

[0002] As a structural joint that prevents buildings from cracking or being damaged due to climate and temperature changes, the post-cast strips of the basement side walls must be poured with concrete after the main structure is capped and the settlement is stable under normal circumstances. After the concrete strength reaches a certain level, the side wall waterproofing, protective layer and backfill construction will be carried out. During the period of waiting for the main structure to be capped and the settlement to be stable, which sometimes lasts for half a year, the slope of the basement foundation pit has always existed, especially in the rainy season, when the amount of rainfall increases, the safety risk of the foundation pit slope is particularly high, and the hidden dangers are particularly prominent. Therefore, a construction method is designed that can backfill the excavation area around the basement in advance without waiting for the main structure to be capped, and does not pour the post-cast strip concrete in advance if the design and specification requirements are not met.

[0003] Analysis of the structure of conventional side wall post-cast strip: Figure 1 As shown in the figure, the two sides of the side wall post-casting strip are the main structures of the side walls that have been cast. The post-casting strip concrete can be cast only after the main structure of the upper structure is capped and the settlement is stable, and then the side wall waterproofing and waterproof protective layer are constructed. The waterproofing material is generally a self-adhesive waterproofing membrane. Finally, the backfill construction around the basement foundation pit is carried out, which usually takes about half a year. During this period, the slope of the basement foundation pit has been exposed to the outside, and the slope of the foundation pit is greatly affected by external factors, posing a greater safety risk.
